Such a beautiful unusual jug for a collection. There is no makers backstamp. Underglaze impression 100 and 5 Gilt no 41. The jug is in used vintage/antique condition. There is a hairline crack on the lip of the jug which extends about 6 cms down the jug. I enjoy this jug so much that its in my little collection until it finds a new home!! There is some loss of colour on some areas. See the pictures. Dont hesitate to ask any questions.
